Statement

Two Transportation Safety Board of Canada (TSB) investigators working on the Ukrainian International Airlines flight 752 accident investigation departed Tehran early Sunday morning, 19 January 2020.

During their 6 days in Tehran, they had several meetings with officials from the Aircraft Accident Investigation Bureau of the Islamic Republic of Iran (AAIB), visited the accident site, and examined the wreckage, which is secured in a separate location.

The TSB investigators continue to work with the AAIB, who have been cooperative and helpful. The TSB continues to assist in whatever way possible.

This week, the TSB investigators will travel to Ukraine to meet with the National Bureau of Air Accidents Investigation of Ukraine (NBAAI) and to collaborate as best they can to help further the investigation.

It is our understanding that the flight data recorder and the cockpit voice recorder—often referred to as “black boxes”—are still in Iran. The AAIB’s investigator-in-charge (IIC) may travel to Ukraine this week to meet with the NBAAI to discuss the investigation and visit the NBAAI recorders lab.

There are still no firm plans as to when and where the aircraft recorders will be downloaded and analyzed. The TSB will deploy a second team of investigators who specialize in aircraft recorder download and analysis once it is clear when and where that work will be done.

The TSB continues to seek accredited representative status under Annex 13 (see the backgrounder and the investigation page).

This is all the information available until further notice.
